System and method for computing burning index score pertaining to crops

Stubble burning is a serious problem resulting in pollution attributable to smog, loss of nutrients in the top soil, and risk of fires spreading out of control. Existing methodologies have attempted to predict burning areas, but have failed to do so because of inefficient sensing mechanism. Present disclosure proposes a system and method to compute burning index score pertaining to crops by detecting harvest season and predicting probable areas of burning by combining current year's crop area map along with harvesting period and historical hot spot information. Computation of the burning index score is accomplished based on inputs received from at least one of satellite imaging, multi-spectral drone based sensing devices and crowdsourcing information. This will help to prioritize the area for taking corrective measures such as training of farmers, availability of resources, optimizing the resources schedule, etc.

The entire contents of the abovementioned applications are incorporated herein by reference.

TECHNICAL FIELD

The disclosure herein generally relates to estimating burning area of crops, and, more particularly, to predict the burning area based on burning index score.

BACKGROUND

Poor air quality is primary cause of various health problems. One of the assignable causes pertaining to poor air quality is crop residue burning. The problem of crop residue burning in prevalent in many parts of the world. Specifically, in some of the Indian states such as Punjab, Haryana and Western part of UP causes air pollution during months after rice and wheat harvesting. This has become a very serious issue all across the world, specifically in northern part of India.

There is an immediate need to predict the probable areas of burning and prioritize the areas to carry out some preventive measures which can reduce the amount of burning. In India, specifically in states of Punjab, Haryana and Western UP, one of the practice followed by the farmers after crop (e.g., wheat and rice) harvesting is burning of the agricultural biomass residue. This not only causes the health hazards but also causes exposure to suspended particulate matter concentration. In agricultural context, residue burning causes loss of nitrogen, phosphorus, sulfur and potassium from the topsoil layer and make the land infertile. There is a long standing technical need to predict, identify and prioritize the areas wherein stubble burning and consequent air pollution may be anticipated.

The database 108 may store information but are not limited to, a plurality of parameters obtained from one or more sensors, wherein the parameters are specific to one or more entities (e.g., user, machine, and the like). Parameters may comprise sensor data captured through the sensors either connected to the user and/or machine. Further, the database 108 stores information pertaining to inputs fed to the system 100 and/or outputs generated by the system (e.g., at each stage), specific to the methodology described herein.

In operation, a flowchart 200 illustrating a method for predicting the burning probability score is shown in FIG. 2. Initially at Step 202, satellite images from one or more satellite sources for a crop to be harvested in an area of interest are obtained. In an embodiment of the disclosure, said crop can be rice. In another embodiment of the disclosure, said crop can be wheat.

At Step 204, for the area of interest, a crop area map using early season satellite time series data derived from the satellite images, wherein the crop area map comprises a plurality of pixels is generated. To identify pertinent crop area of interest amongst the land area one or more machine learning based classifier such as random forest may be utilized by the system 100. FIG. 3 depicts a crop map obtained through satellite imaging, according to an embodiment of the present disclosure.

Next at Step 206, for the specific crop, a Start of the Season (SoS) information pertaining to each of the plurality of pixels comprised in the crop area map using the early season satellite time series data is extracted from a Crop Information Database. In an embodiment of the disclosure, For instance, for each rice pixel/field, start of the season information may be computed as described below:

    • Satellite images S1, S2, . . . , St during the transplanting window are obtained. Backscatter values for each pixel and associated date for that satellite image are stored as key-value pair, for example, Sv1-Sd1, Sv2-Sd2, . . . , Svt-Sdt.
    • Minimum value during transplanting MinV=min(Sv1, Sv2, . . . , Svt)
    • Date associated with min value SoS is obtained as SoS=Date(MinV)

At Step 208, for a current season, an End of Season (EoS) map is computed/generated based on the SoS information and sensory information associated thereof. In an embodiment, the sensory information comprises at least one of temperature, relative humidity and Carbon di-oxide (CO2) pertaining to the area of interest. For instance, EoS map may be derived as a function SoS information and data from various sensors pertaining the crop area, wherein the EoS map (or also referred as EoS) may be derived by way of following expression as depicted below:
EoS=f(SoS, data from sensors)

FIG. 4 depicts an End of Season (EoS) crop map according to an embodiment of the present disclosure.

At Step 210, for a given time window for the current season, at least a fraction of the area for harvesting the crop (HFa) is computed using the crop area and the EoS map. For example, for each time window (12 days in this case), the fraction of area to be harvested is computed using total rice area (or total crop area) and EoS

Assuming week start DoY is 285 and end DoY is 296

Area to be harvested in a time window, (Hw)=No of pixels in EoS with value between 285 to 296*Pixel area. In another words, harvesting area (Hw) for the given time window is computed based on number of pixels in the EoS map and pixel area associated with the number of pixels.

Further total crop area (Ht) is computed based on number of pixels of the crop in the EoS map and the pixel area associated thereof. Total crop area (in this case total rice area) may be computed and expressed by way of following equation:
Total Crop Area Ht=Total no of crop pixels*Pixel area

Based on the area to be harvested (Hw) and the total crop area (Ht), the fraction area to be harvested is computed by way of following expression:
Fraction area to be harvested, HFa=Hw/Ht

Sample value of HFa in an embodiment of the disclosure is 0.2. In other words, in an embodiment of the disclosure at least a fraction of the area for harvesting the crop is determined by computing harvesting area (Hw) for the given time window based on number of pixels in the EoS map and pixel area associated with the number of pixels; and computing total crop area (Ht) based on number of pixels of the crop in the EoS map and the pixel area associated thereof. Referring now to FIG. 5, a Region of Interest (RoI) marked with the numerical “294010” indicates a probable harvest area in hectares pertaining to a crop during day of the year, DoY 285 to 296. In one embodiment, the Region of Interest (RoI) may indicate a Taluka or a district in a State. It may also designate a logical governance unit.

Referring now to FIG. 6, a Region of Interest (RoI) marked with the numerical “1817602” indicates total harvest area in hectares pertaining to a crop during day of the year, DoY 285 to 296. In one embodiment, the Region of Interest (RoI) may indicate a taluka or a district in a State.

Referring now to FIG. 7, a Region of Interest (RoI) marked with the numerical “0.16” indicates percent harvest area in hectares pertaining to a crop during day of the year, DoY 285 to 296. In the instant example, percent harvest area is computed as a ratio of harvest area to the total harvest area
0.16=294010/1817602

In an embodiment of the disclosure an average area burned in the given time window (Bw) is computed based on (i) number of burnt pixels for the given time window and associated pixel area and (ii) total number of burnt pixels, comprised in the crop area map. Further, average total burnt area (Bt) is based on (i) total number of burnt pixels and associated pixel area thereof, comprised in the crop area map using a historical burned area data. Referring now to FIG. 8, a Region of Interest (RoI) marked with the numerical “0.04” indicates percentage area burnt pertaining to a crop during day of the year, DoY 285 to 296. This is estimated from average area burnt in last few years during DoY 285 to 296 in said taluka or associated governance unit thereof and average total area burnt in said taluka or associated governance unit thereof.

At Step 214, a Burning Index Score (BIS) pertaining to the area of interest where the crop is to be harvested based on HFa and BFA, wherein Burning Index Score (BIS) represents a potential harvesting region associated with burning of the stubble is determined.

Referring now to FIG. 9, a Region of Interest (RoI) marked with the numerical “0.01” indicates burning index score pertaining to a crop during day of the year, DoY 285 to 296 based on percent area harvested and percent area burnt during DoY 285-296 for said taluka or associated governance unit thereof.

Referring now to FIG. 10, a Region of Interest (RoI) marked with the numerical “0.01” indicates burning index score convex pertaining to a crop during day of the year, DoY 285 to 296 based on percent area harvested and percent area burnt during DoY 285-296 for said taluka or associated governance unit thereof.

For instance, burned area in each cluster (taluka/village) for last 10 years from MODIS burned area product/VIIRS are first obtained. Moderate Resolution Imaging Spectroradiometer (MODIS) and Visible Infrared Imaging Radiometer Suite (VIIRS) are the satellites/sensors which can be used to derive burnt area.

Assuming week start DoY is 285 and end DoY is 296
Average Area burned in a time window, (Bw)=Average No of burnt pixels between DoY 285 to 296*Pixel area
Average Total Burnt Area Bt=Total no of burnt pixels*Pixel area/Total no of years
Burnt fraction area BFa=Bw/Bt
Burning Index Score=HFa*Bfa

In the present disclosure, Burning Index Score is computed as described below by way of example:

Average area burned in the given time window (Bw) is 2500 Hectre area (Ha) and

Average total burnt area (Bt) is 20000 Ha
Burnt Fraction Area=BFa=Bw/Bt=2500/20000=0.125
Burning Index Score=Hw*Bfa=0.2*0.125=0.025

The burning index score is computed as a product of HFa and BFa.

In an embodiment of the disclosure, real time data specific to weather forecast pertaining to the area of interest (ROI), a set of high resolution images of the crop, captured by a multi-spectral drone based sensing device and crowdsourcing information is obtained. Further, the Burning Index Score (BIS) based on the obtained real time data is dynamically updated. Further, multi-spectral camera with 8 bands covering Visible, Near Infrared (NIR) and Shortwave Infrared (SWIR) sensors are used in certain implementations. The information in NIR and SWIR bands is deployed to get accurate insights on harvested areas and/or burned areas so as to update the burning index score. Specifically in areas where there is a high probability of burning and low confidence on the burning index score, the data obtained through multi-spectral camera can be augmented with satellite based scores to obtain a higher degree of precision.

Crowdsourcing information can comprise data specific to geo tagged information, for example, images of the crop, incidence of burning, surrounding ambient and any other data that affects crop harvesting. In one embodiment, images of the crop, may further include latitude and longitude information of field where incidence of burning is taking place. This information may be further utilized for updating the burning index score by performing the steps 212 through 214. In certain scenarios, to compute updated burning index score in real time, the system may rely upon (i) information retrieved from, and captured by the multi-spectral drone based sensing device (ii) output of Steps 202 till 210, and (iii) sensory information obtained from sensors deployed in region of interest.

Present disclosure proposes a system and method to detect the harvest season, predict the probable areas of burning by combining the current year's crop area map along with harvesting period and historical hot spot information. This will help to prioritize the area for taking corrective measures such as training of farmers, availability of resources, providing information on appropriate government schemes, optimizing the resources schedule, etc.
